Seal services for securing electronic documents

The electronic seal confirms the origin and integrity of a digitally transmitted document and is essential for the further digitalization of public authorities and companies.

eSeal boosts digitalization

Electronic seals – eSeals for short – ensure the origin of documents and protect against any unnoticed subsequent changes. eSeals are always issued to a legal entity, i.e., a public authority, an organization or company. The eSeal is much like traditional company stamp or official seal but in digital form. An eSeal shows the recipient of a digital document the institution that issued the document and that the document is genuine, i.e., unaltered.

In public administration, using eSeals can help to improve electronic services and save time thanks to digital document dispatch. This means that notices no longer have to be in written form, but can be sealed and transmitted electronically. The documents are then electronically archived, ensuring the origin of the document. When important government documents, such as certificates, are issued, eSeals prevent fraud.

Qualified Seal Card or the Qualified Seal ID

D-Trust offers two seal solutions, i.e., the Qualified Seal Card and the advanced digital seal (Qualified Seal ID). Both seal services comply with the requirements of the eIDAS Regulation and are legally recognized. The Qualified Seal Card is a smart card that can be used wherever a qualified application is required to ensure the authenticity and integrity of a document: for instance, in e-tendering or for substitute scanning according to the ‘Technical Guideline 03138 Substitute Scanning’ (TR RESISCAN) of the Federal Office for Information Security (BSI).

The Qualified Seal ID is based on a qualified certificate and requires neither a card reader nor middleware. The cryptographic keys are stored as software tokens on a self-selected memory, for instance, a company or public authority server. The advanced seals generated by the soft token can be used when a qualified seal is not required, for instance, to confirm receipt of a letter or confirm attendance.

Our sealing services in comparison

Both seal services from D‑Trust provide security when it comes to distributing and using electronic documents. Qualified electronic seals are required for some procedures. In the case of many other procedures without formal requirements, advanced electronic seals provide certainty for users and senders who are then free in their choice of seal solution.
